Microsoft’s installer says this Windows 10 PC can’t move to Windows 11. But hundreds of actual people with so-called “incompatible” machines have decided otherwise. Of about 400 user reports, there were no costs for new hardware and most had successfully completed the upgrade and were continuing to receive monthly security updates after the upgrade.
Why those PCs were tagged ‘incompatible’
Windows 11’s hardlists are pretty established at this point: a small list of supported CPUs, TPM 2.0, and Secure Boot. Microsoft has characterized these as security and reliability guardrails, citing measures such as virtualization-based security and hypervisor-protected code integrity. In Microsoft’s own security communications, those layers have been associated with significant declines in malware on test devices.
The real-world result is that on a lot of still-usable systems (that have older CPUs or APUs), users can’t install Windows 11 at all.
Most of those machines are shipping with an implemented fTPM with which Secure Boot could work even though they are also failing the CPU list. Users were encouraged to replace otherwise good laptops and desktops.
How 400 owners upgraded, regardless
There where two dominant upgrade path reports: The first is a path to upgrade in-place in Windows 10 from a supported registry value that instructs Setup to bypass the CPU family/date check and allow a TPM 1.2 with some exceptions. This technique is already documented for I.T. Pros on Microsoft’s support and deployment sites, and is used in enterprise environments to support edge cases.
Second, a clean or in-place install with current Windows 11 media. A lot of them were using flash drives and another similar software which can prevent compatibility checking during an installation. Readers have constantly reported that the clean install of a Windows 7 image built from a Microsoft TechNet ISO worked perfectly the very first time (and that they would use this same image on all of their deployments).
What went wrong — and how they fixed it
Most snags were garden-variety setup problems, not fatal incompatibilities. Most instances were attributed to a bad registry entry, like a typo, using the wrong type, or in the wrong subkey, and leaving the installer to continue with CPU checks. Yes, the value was wrong in the right location that made the upgrade do its work.
It was an upgrade abort with a generic failure message, is what would commonly happen. In that situation, downloading a fresh ISO, rebooting and running the installer in the regular way fixed it. A minority received a “Your PC isn’t supported yet” message, a Microsoft safeguard hold instigated by a known app, driver or device issue. Windows Release Health Dashboard has frequently made note of such holds. Users got around the block by unplugging peripherals and updating BIOS and drivers or uninstalling the offending third-party code.
Do they still get updates?
Yes, most of these users reported that they received monthly security updates even after they upgraded. While Microsoft’s guidance doesn’t go so far as to promise updates to unsupported hardware, past enterprise guidance and real-world experience have proved that security patches still manage to find unsupported devices. Feature updates can be a bit less reliable: certain older hardware, it seems, won’t accept some of them directly, but a so-called in-place upgrade using the current installation media generally works.
There are trade-offs. Some security features—such as full Device Encryption—need TPM 2.0 to function at their peak level. And in case of a device that is dependent on some very old drivers, a ^Future Windows 11 release may require you to manually upgrade cycle or clean up the driver.
Why Microsoft is holding the line
Microsoft has been prioritizing security and reliability, and those are valuable priorities. But the harsh CPU cutoff does also line up closely with how the industry reacted to Spectre and Meltdown. Those side-channel bugs were found in nearly every popular CPU sold for years, and the mitigations from chipmakers and operating systems came with performance penalties. Information from certain organizations such as US-CERT and NIST suggested fixes involving firmware and microcode, and in some cases hardware replacement for complete mitigation.
By limiting the support matrix, Microsoft can reduce the permutations of processors, drivers, and firmware it has to test at scale. OEMs also want a cleaner, up-arrowed baseline. None of that will make the message — buy a new PC — go down any easier for owners of high-end machines that fall just shy of the cutoff point.
What it all means for consumers and IT
The practical takeaways from these 400 upgrades are. If your machine just misses the CPU list but can run Secure Boot and TPM 1.2 at least, you’ll probably be fine to install Windows 11 with no hiccups. Maintain a recent backup, employ virgin media, check the registry setting if you go the in-place path, and eliminate unnecessary peripherals at install time. Look for security updates to continue, but be ready to rinse and repeat an in-place upgrade for major releases.
This is similar to what many already do under controlled risk: apply Microsoft’s documented “compatibility hold” exemptions for certain device cohorts, watch Windows Release Health, and have a rollback path. Increasing the useful lifespan of stable hardware can uncage the budget for the places where new silicon actually means something — workloads that can benefit from AI acceleration, greater battery life or modern Wi-Fi and Bluetooth stacks.
Microsoft’s compatibility stance isn’t going to flip overnight. But this kind of real-world result demonstrates that “incompatible” doesn’t always mean “impossible”—and for hundreds of users, Windows 11 upgraded as uneventfully as Microsoft said it couldn’t.
